Artwox wooden decks

While surfing, I discovered Artwox Models who make wooden decks for ship models. I found out that they even do one which would fit for my Zvezda Varyag. And they are very cheap, only 15 Dollar for the Varyag deck.

On the pics the deck looks very good and thin, but did anybody use one of these decks already? How is the quality? Why are they so cheap? Other decks cost 3 times as much! Are the decks made of real wood or is it another material?
